Part 1: What You Must Know About Password-Protected PDF Files

If you see "Secure PDF", it means that the PDF file has been encrypted, that is, protected by a password. But in fact, what you need to know is that PDF files actually have 2 different types of passwords: open password, permission password.

1.Open password of PDF files

Open password, also known as access password, requires users to enter a password before opening to view the contents of PDF files, thus restricting access to PDF files to protect PDF file information from being leaked.

2.Permission password of PDF files

The permission password can restrict users from using certain features of the PDF, such as editing, copying, printing, to ensure that the information in the PDF file is not modified or deleted. When users want to modify the content of the PDF or remove these functional restrictions, they must first enter the permission password.
